Bootstrap should be the de facto front-end toolkit for this project.

Many of the files in the Werkzeug package are set to 755. Batch process them with the following to remove the exec bits.

 find . -type f -print | xargs chmod 644

If I run the testrunner.py file as desribed, I get an ImportError because the main module cannot be found:

python testrunner.py ~/Downloads/google_appengine/
Traceback (most recent call last):
  File "testrunner.py", line 36, in <module>
    main(SDK_PATH, TEST_PATH)
  File "testrunner.py", line 21, in main

ImportError: No module named main

I found out (thanks to git/github :)) that once there was a src/main.py file, which was removed for any reason: d848bea

Why was it removed? Is it really no longer needed? If yes, what am I doing wrong or in an outdated way? If it's still needed: give it back!

Replace deprecated csrf_token attribute with hidden_tag method in form-based templates.

The deprecation warning is issued in Flask-WTF 0.3.

Would be awesome for new users to have https://github.com/thadeusb/flask-cache as a default extension.

Hi,

I love this project, it helped us a lot getting flask deployed on gae.

The simple examples were simply awesome to understand the underlying ndb as well. Very useful indeed.

I have a suggestion for this project:

One thing that is missing though, is paging in ndb and how to handle that in flask.

There is this excellent paging demo in flask, which however uses SQLAlchemy:

https://github.com/mitsuhiko/flask-feedback

demo to be seen online:
http://feedback.flask.pocoo.org/

I was trying to adjust that to use ndb instead of alchemy, and can't get it fully right.

def show_feedback(kind, page):
    """Renders returned feedback."""
    curs = Cursor(urlsafe=request.args.get('cursor'))
    feedback_for_page, next_cursor, more = Feedback.query().filter(Feedback.kind==Feedback.KINDS[kind]).order(-Feedback.pub_date, Feedback.key).fetch_page(page, start_cursor=curs)
    return render_template('show_feedback.html', kind=kind, feedback_for_page=feedback_for_page, next_cursor=next_cursor, more=more)

It would be so awesome providing an example snippet in this project how to use gae-paging within flask.

Regards,
Hooman

The Flask docs specify how to leverage Jinja2 template macros to streamline form field generation. The example forms in this app should demonstrate how to use the render_field method to provide a field-generation option for developers.

Add the Flask-DebugToolbar (http://flask-debugtoolbar.readthedocs.org)

maybe try linking to "git clone" the https URL in the readme?

Incorporate werkzeug-debugger-appengine to enable Werkzeug's interactive debugger when running the local development server.

I can't find any form nor template that defines the login screen.
Is this defined by google app engine? How can this be overridden?

Message from Dan Jacob sent to Flask email list on Feb 9, 2011:

"As with frameworks such as Django and Ruby on Rails, Flask-WTF skipped
CSRF validation in the case of AJAX requests as it was deemed safe
enough due to browser same-domain policies. This was to make it more
convenient when writing AJAX code.

However it has since come to light that some browser plugins have made
this feature insecure. A more complete discussion can be found here:

http://www.djangoproject.com/weblog/2011/feb/08/security/

From the latest version of Flask-WTF, 0.5.2, AJAX requests will
automatically do CSRF validation in the same way as any other POST
requests. You can disable this feature by setting CSRF_ENABLED to
False in your settings or by passing csrf_enabled=False in your form
constructor, but this is entirely at your own risk and is not
recommended for production sites.

It is recommended you upgrade to the latest version of Flask-WTF (0.5.2)."

The README document shows that unit tests are in src/application/tests.py file, which originally turned me off as I have too many unit tests to place in a single file, plus it mixes test code in with application code.

However it looks like the actual directory layout contains tests in a separate src/tests/ directory, which is more scalable and keeps the test code nicely separated. So this is a request to fix that documentation error in the README :-)

Hi Kamal,

I have downloaded the latest and followed the instructions:

This is the structure I have.

Yet when I run the application:

(f11-env)hooman@pc:~/workspace/F11-GAE$ ~/workspace/google_appengine/dev_appserver.py src/

it fails, saying that

    from flask_wtf.form import Form
ImportError: No module named flask_wtf.form
INFO     2013-06-18 15:09:47,381 server.py:593] default: "GET /_ah/warmup HTTP/1.1" 500 -

But I can see the file in the virtual-env installed.

This is the stack I have installed:

simplejson
Babel==0.9.6
Flask==0.9
Flask-Babel==0.8
Flask-Login==0.2.2
Flask-WTF==0.8.3
Jinja2==2.7
MarkupSafe==0.18
WTForms==1.0.4
Werkzeug==0.8.3
argparse==1.2.1
isodate==0.4.9
passlib==1.6.1
python-dateutil==1.5
pytz==2013b
rauth==0.5.4
requests==1.1.0
speaklater==1.3
wsgiref==0.1.2

In Eclipse all these imports are marked as red as well.

How can I solve these namespace problem? I was expecting this project to solve that problem in first place. :)

Many thanks for advice,
houmie

Hello,

thanks for maintaining this project, it's really cool useful.

The only problem I've found concerns running the tests in the template. In the tests.py there is a note that the code needs to be updated to Python 2.7 runtime, and I see that there was an issue here on github some time ago concerning this. I think it may be useful to open the issue once again.

I've fiddled around with this for a while, I've went through appengine docs on testing and simply took the code of their testrunner and added it to my app root directory (structure of which is based on your template), I had my own tests and edited them too to fit with gae.

The tests run ok and I'm partly happy with that but the only thing that bothers me is that my tests do not load testing configuration for flask's app.test_client. The tests take their configuration from main application directory and they ignore testing configuration that I pass to them in my tests setUp() method. This is not the end of the world since I'm still on localhost now, so I can find some ways to bypass this, but it slowly starts to irritate me and I'd like to improve this somehow.

So if anyone knows something that might be helpful here I'd be grateful about any information.

Once again thanks for maintaing the project!
Cheers!

The new location is http://localhost:8000

The zip package archives (in the src/packages folder) should be created without compression (via zip -r0 ...) for quicker warmup and serving performance.

Werkzeug's session key handling converts secret keys to strings, throwing a UnicodeDecodeError when the keys are encoded/decoded via base64.

The debugger seems to be broken.

Replace HTML5Boilerplate's reset CSS styles with YUI 3 Reset/Fonts/Grids and Base CSS framework.

The Flask documentation section covering signals mentions a dependency on the blinker library, which should be added to the boilerplate project template.

Add a URL dispatch configuration file (urls.py) to decouple the URL route configuration from the view file, using the Flask app object's add_url_rule() method, allowing the application to gracefully handle larger application structures.

In "app.yaml":

handlers:

• url: /_gae_mini_profiler/static
  static_dir: packages/flaskext/gae_mini_profiler/static

should be:

handlers:

• url: /_gae_mini_profiler/static
  static_dir: flaskext/gae_mini_profiler/static

See "packages" in "static_dir"

I suggest putting
DEBUG_MODE = True
in the /application/settings.py
because this flask-appengine-template is a starting point for a new project, and the debug mode is usually put in "True".
Obviously that should be reflected in the README file as an hint there too.

Thanks,

After several projects on appengine and a recurring set of problems i thought about writing a template myself, but before doing that i set out to look at what exists... So i've played around with flask-appengine-template and @lipis gae-init ( http://gae-init.appspot.com/ ).

I'm not sure you're aware of each others' project, but I thought i'd let you know. Each of your templates is very cool on its own already. Still i think that joining forces would maybe create something even cooler. Even should you disagree (which is understandable considering the amount of work you both must've put into each of the projects), i still think it's worth looking at each others template cause some things are solved better here, some things better there. So some of the differences i've found:

gae-init:

• nice (kickass) oauth integration with flask-login
• lessCSS and coffescript support
• deployment support: minification, library zipping
• i18n support in gae-init-babel

flask-appengine-template:

• cool gae-mini-profiler & debug toolbar integration
• uses virtualenv & pip for dependencies (why not for the internal libs as well?)
• some test snippets (even though a bit old maybe)

So give it a try...

Bit off-topic but as gae-init is on mercurial: there's pretty cool hg via git support: http://felipec.wordpress.com/2012/11/13/git-remote-hg-bzr-2/

PS: also posting this on gae-init as an issue: https://bitbucket.org/lipis/gae-init/issue/6

I'm trying to start default application.

Configure /static folder in App Engine (app.yaml directive) rather than in Flask, to allow expiration headers to be configured in the app.yaml file.

Hello,
Thanks for creating this template, it's been helpful in getting a quick bootstrap to GAE devserver running. I was attempting to use the latest Flask documentation, but quickly realized that the version in this template is 0.9 and not the latest. I attempted to update the Flask library, but it requires the "itsdangerous" module. I've installed this, but Flask doesn't appear to find it. If you're not able to upgrade the template, do you have any ideas why this might be happening and how to resolve it? Thanks.

Guys, not sure if anyone came across that:
If I run this in the terminal (Mac)

 export FLASK_CONF=DEV

and then start the app through dev_appserver.py src/ but logging.info() shows it has not loaded the development environment.

Same is in Eclipse:

Even though Eclipse.s environment is set to FLASK_CONF=DEV the break point never goes into if os.getenv('FLASK_CONF') == 'DEV':. When I run the tests though, I see elif os.getenv('FLASK_CONF') == 'TEST': is hitting.

if os.getenv('FLASK_CONF') == 'DEV':
    #development settings not to be used in production
    app.config.from_object('application.settings.Development')
    # Flask-DebugToolbar (only enabled when DEBUG=True)
    toolbar = DebugToolbarExtension(app)
    # Werkzeug Debugger - enabled by default in new versions of Flask 
    #if you set debug to true, right?
    # app.wsgi_app = DebuggedApplication(app.wsgi_app, evalex=True) 
elif os.getenv('FLASK_CONF') == 'TEST':
    app.config.from_object('application.settings.Testing')

Why is this not working anymore. Anyone came across that yet?
Many Thanks for your help,
Hooman

Re-enable support for Flask Debug Toolbar.

Libraries can be packed in zips that will be unpacked whenever they are needed. This makes things cleaner and saves some space but makes more startup overhead. Do you think this is a good idea?

Create an "admin required" decorator to allow views to be protected by an admin-only flag.

Hi Kamal,

I just downloaded it and ran "make setup" it ended with the PIL error.

May you please be so kind and advice?

Many Thanks,
houmie

After some more research, it seems that the make file is not activating the created virtualenv after all. Hence the installation seems to happen on the main OS python, hence the permission problem. Best is to remove the make file or fix it properly.

Many Thanks

seems, google already wrap up for their blobstore of images.

it is really good to have some examples for how i can upload images in flask, since they are different from flask and web2app?

Right out of the box I have attempted to add an ndb.KeyProperty to models.py, and end up with an error saying that KeyProperty has no attribute _reference_class. I've traced this down to line 329 in /src/lib/wtforms/ext/appengine/ndb.py:

kwargs['reference_class'] = prop._reference_class

It appears to be looking for 'reference_class' which is an old db.model idiom. The analog for ndb is kind, but swapping out line 329 with an instruction to look for the kind attribute just results in a deeper set of issues.

kwargs['reference_class'] = prop._kind

Only support macosx?I'm running the demo on windows,so how to fix that?And what's pkg_resources.py used for?

From code here: https://bitbucket.org/simplecodes/wtforms/pull-request/16/added-ndbpy-for-compat-with-ndb-project/diff

I would create a pull request, but I'm not sure how to properly attribute the code and licenses.

I generally don't put the libs into my git repository and use make setup to download them instead.

I was wondering if I could delete lib/gae_mini_profiler and install it via pip?

pip install gae_mini_profiler

But I can't find any way to achieve this. Please advice if you know a way.

Many Thanks,
Houman
